You play a game that involves drawing two numbers from a hat. There are 25 pieces of paper numbered from 1 to 25 in the hat. Each number is replaced after it is drawn. Find the probability that you will draw the 3 on your rst draw and a number greater than 10 on your second draw.

Answers

Answer 1

Answer:

$Probability=(3)/(125)$

Step-by-step explanation:

In the question,

Total number of pieces of paper numbered from 1 to 25 are = 25

As the draw also includes replacement.

So,

Probability of drawing '3' is given by,

$Probability=(Favourable\,outcomes)/(Total\,cases)\nProbability=(1)/(25)$

Now,

Numbers greater than 10 are = 15

So,

Probability of drawing a number greater than 10 is given by,

$Probability=(15)/(25)$

So,

Total probability is given by,

Product of probability of drawing 3 in 1st draw and the Probability of drawing a number greater than 10.

$(1)/(25)* (15)/(25)=(3)/(125)\nProbability=(3)/(125)$

You have a balance of $15,300 on your credit card with an annual interest rate of 185(1.5% interest rate per month) You pay $200 this month. Did your balance go up or down?

Answers

Down

Normally, payment is first applied to interest before it is applied to the principal. Since your payment is larger than the interest, your remaining balance will go to the principal. As a result, your balance will go down.

If f(x)=3x+2, find f(f^-1(14))

Answers

Answer:

Step-by-step explanation:

f(x) = 3x + 2x = 3f-1(x) + 2x - 2 = 3f-1(x)(x - 2)/3 = f-1(x)(14 - 2)/3 = f-1(14)12/3 = f-1(14)4 = f-1(14) f(f-1(14)) = f(4)f(4) = 3(4) + 2f(4) = 12 + 2f(4) = 14 A function and its inverse are inverse operations, like addition and subtraction. They undo each other. f(f-1(x) = x
